Patented June 16, 193ll- UNITED STATES NOEL PLATEL, OF TO'I'OWA, NEW JERSEY .HAIR CTiRLING DEVICE Application filed. February 18, 1929. Serial No. 340,998.

This invention relates to hair curling devices and in particular to devices of this class in which the hair, coiled, is placed in a closed box or container to which, usually, steam is admitted. Heretofore the box has been made of metal. In consequence it was necessary not only to provide yielding means, as a rubber gasket, formed separately from the wall structure of the box, for sealing its joint and thus confining the steam during the curling operation, but it was necessary also to guard against burning the person being treated while the treatment was going on and also the operator in handling the box after a treatment, as by placing a spacing clamp or other device on the hair between thebox and the patients head and by the operator waiting a suitable length of time after a treatment to allow the box to cool. lhe object of this invention is to provide a curling device of this type which,

though steam may be used in the curling operation, will not be adapted to burn either the patient or the operator and which will be steam tight and securely hold in the form of a coil the hair within its steam space and which will further be simple in construction, easy to assemble and disassemble and facilitate the treatment for which it is intended.

In the drawings,

Fig. 1 is a side elevation of the device;

Figs. 2 and 3 are vertical sections on the lines 22 and 3-3, respectively, Fig. 1;

Fig. 4 is a vertical section of the part of the box which I term the cover;

Fig. 5 is a plan of that part of the box which I term the body;

Figs. 6 and 7 are side and end elevations of the spindle; and

Fig. 8 is a side elevation and a transverse section of an elastic band or strap for the box.

In the example illustrated, the box is made in two main parts, a body 1 and a cover 2, these being preferably substantial counterparts, as by bein each semi-cylindrical, with closed ends, an having the edges thereof which meet when they are combined to form a cylinder provided the one with a continuous tongue 3 and the-other with a continuous groove 4 which snugly fit each other. One

of the parts, as 2, may have a centrally projecting nipple 5 provided with a bore 6 communicating with its exterior and on to which nipple a rubber tube to be connected to a steam source may be fitted. One part, as 2, ma also have vents 7 for escape of the steam.

c that the box may not burn either the patient or the operator its sections are formed of some material which is, relatively to metal, a poor conductor of heat, as rubber, molded to the proper form. As will be understood, a flat wisp of hair, when the device is in use with the hair coiled in the box, is to extend between the tongued and grooved portions ofthe body and cover along one longitudinal side of the box, and the space within the box should be sealed from the atmosphere so as to prevent undue escape of steam. The box should be adapted for sealing of the joint between the two sections, body and cover, notwithstanding the interposition of the hair, and yet the two sections should have suflicient stability or stiffness so that they can be pressed together to form the seal and not in fact be distorted so as to disturb the seal. Therefore I mold each section so that the joint-forming portion thereof is of yielding elastic rubber and the remainder is of rubber having appreciably less, if any, ability to yield. The plane of demarcation between these two portions of each section of the box is indicated in Fig. 2 by line a (this being more or less approximate), such plane being parallel with the plane of joint. 7

Regardless of the treatment to which the wisp of hair is to be subjected, the box described essentially comprises sections fitted together edge to edge to form an enclosed space for such wisp and having edge portions of the sections coactive to grip such wisp between them, the section including at least one such edge portion consisting of an integral mass of plastic material (as rubber or a rubber compound) formed as to such edge portion yielding and elastic and as to its remaining portions appreciably less yielding.

One section, as the body, has radial grooves 8 formed in its end walls; the other has opposite abutment means, as two radial studs 9 projecting inwardly from its semi-cylindrical wall.

The spindle 10 on which the hair is coiled as a core is split longitudinally from one end and has flattened trunnions 11. The two legs of the thus divided s indie having been spread apart the end ot the wisp of hair is inserted therein so-as to become clamped by the spindle upon permitting it to assume its normal state (full lines, Fig. 6). Then the coil having been tightly formed by rotating the spindle the latter is introduced into the body 1 of the box with its flattened tongues engaged in the grooves 8 which hold the spindle against rotation. After the parts have been assembled in this manner, any means for holding the body and cover of the box together and in sealing relation to each other may be used, as elastic rubber bands 12, such as that shown in Figs. 8 and 9, these embra-ring the box as shown in Fig. 1. The abuzinents 9 are present so that in those instances where the size of the contained package (the pindle 10 and coil of hair thereon) is such that the tongues 11 would be caused to in'ipress the edge of the section 2 and so perhaps cause steam leakage said abutments will hold the package depressed in the section 1, or with its said tongues below the plane of meeting of the two sections. In this, it will be seen that the package is clamped between and by the sections of the box, which so far as I know is new in devices of this class.

Having thus fully described my invention, what I claim is:

1. A box to contain a wisp of hair to be treated comprising sections fitted together edge to edge to form an enclosed space for such wisp and having edge portions of such sections coactive to grip such wisp between them, the section including one such edge portion consisting of an integral mass of plastic material having low heat-conductivity and being formed as to such edge portion yielding and elastic and as to the remaining portion thereof appreciably less yielding, and means, holding said edge portions pressed together, for maintaining said sections in the edge to edge relation.

2. A box to contain a wisp of hair to be treated comprising sections fitted together edge to edge to form an enclosed space for such wisp and having edge portions of such sections coactive to grip such wisp between them and shaped to form, together, a tongueport and-groove joint, the section including one such edge portion consisting of an integral mass of plastic material having low heatconduetivity and being formed as to such edge portion yielding and elastic and as to the remaining portion thereof appreciably less yi -lding, and means, holding said edge pressed together, for maintaining said sections in the edge to edge relation.

3. A box to contain a wisp of hair to be treated comprising sections fitted together edge to edge to form an enclosed space for such wisp and having edge portions of such sections coactive to grip such Wisp between them, the sections including such edge portions each consisting of an integral mass of plastic material having low heat-conductivity and being formed as to such edge portion yielding and elastic and as to the remaining portion thereof less yielding, and means, holding said edge portions pressed together, for maintaining said sections in the edge to edge relation,

4. A device to contain a hair package to be treated comprising a sectional box and means to secure the sections of the box together to form an enclosed space for the contained package, said sections having means within said space to exert pressure on the contained package.

5. A device to contain a wisp of hair to be treated comprising a sectional box, a core'in the box removable therefrom on separating the sections thereof and on which the hair wisp is adapted to be coiled, and means to secure the sections in box-forming relation to each other, one section having at one end a transverse groove and the core having one end snugly fitting said groove and formed with a flat face bearing against one side of the groove and thus holding the core positively against turning.

6. A device to contain a wisp of hair to be treated comprising a sectional box, a core in the box removable therefrom on separating the sections thereof and on which the hair wisp is adapted to be coiled, and means to secure the sections in box-forming relation t each other, said sections when secured in such relation exerting clamping pressure on the core and said core and one section having a separable tongue-and-groove connection opposing rotation of the core.

7 A box to contain a wisp of hair to be treated comprising sections fitted together to form an enclosed space for such wisp and having their meeting portions coactive to grip such wisp between them, the section including one such portion consisting of a unitary body of splastic material having low heat-conductivity and being formed as to such portion yielding and elastic and as to the remaining portion thereof appreciably less yielding.

In testimony whereof I aiiix my signature.
